Question

I am trying to extract some info from a website using simple_html_dom.

Currently I am using:

foreach ($html->find('div.product') as $results) {
    foreach ($results->find('div.image') as $img) {
        echo $img;
    }
    foreach ($results->find('a.title') as $title) {
        echo $title->plaintext;
    }
    foreach ($results->find('div.price') as $price) {
        echo $price;
    }
}

Which works fine. However I need to be able to echo each variable outside of the foreach loop. If I do that using the above code, only the final result will be displayed, i.e. out of the 10 products I am trying to extract only the 10th will be displayed.

Is there a way I can use an array to store all the results from each foreach loop then echo them out once the overall loop is finished?

Something like this:

foreach ($html->find('div.product') as $results) {
    foreach ($results->find('div.image') as $img) {
        array($img);
    }
    foreach ($results->find('a.title') as $title) {
        array($title->plaintext);
    }
    foreach ($results->find('div.price') as $price) {
        array($price);
    }
}
echo array($img);
echo array($title);
echo array($price);

Sorry if this question is confusing I don’t have the best grasp on PHP, especially arrays!

Answer 1

$array_img = array();
$array_title = array();
$array_price = array();
foreach ($html->find('div.product') as $results) {
    foreach ($results->find('div.image') as $img) {
        $array_img[] = $img;
    }
    foreach ($results->find('a.title') as $title) {
        $array_title[]= $title->plaintext;
    }
    foreach ($results->find('div.price') as $price) {
        $array_price[]= $price;
    }
}
echo '<pre>';
print_r($array_img);
print_r($array_title);
print_r($array_price);
echo '</pre>';
